All it takes is to read the book I just bought on engine mechanics, realize what a stupidly horrible design piston engines are (seriously, they destroy themselves by the mere act of running. The internal stresses are unbelievable). Now, imagine an engine that makes sense, and you have a rotary.

 

Yea... too bad the rotary engine is torqueless, thermal ineficient machine with low reliability. And on top of everything, drinks gas like crazy!

hmmm... those stupid piston engines.....

 

Torqueless? Yes, if not turbocharged. Thermally inefficient vs. piston counterpart? Yes. Less reliable? No way. Try this: Run a S2000 and RX-8 both to 8000 RPMs and leave 'em there, and see which one grenades first. People constantly lambaste the reliability of the rotary and they do it without any concrete proof.

 

What could be more durable than a motor that can sit at the fuel cut-off for more than 10 minutes with no coolant!

i want to eat that dorito

 

So why is it that you find more engine replacement posts in a forum like rx8.com than in any other forum... (especially for engines under 100k)?

 

Maybe because people don't understand the basic principles of the engine and the few miniscule things it needs for longetivity. By the way, since you claim such a high attrition rate, maybe you can tell us what percent of cars had their motors replaced.

 

A spinning gas hog.

 

you're simply making this up and don't have any actually facts that state this. We know we know, we all get you, you don't like the rotary engine and will purposely act negative in order to get a fire started in here. Let me guess whats next the gas mileage. Say us all the trouble with the negative posts, we can see you coming a mile away.

 

I don't know about that ... but think about it this way:

Mazda is the ONLY car company with the skills / and the ballz to continue production / development on a totally unique engine .. All the other car companies simply feed off all the engine developments that have been made for the piston engine over time!!!

Simple example : variable valve timing- Started by Honda ( i think) as Vtech" - now (in one form or another) in tons of cars.


Imagine how kick *** the rotary could possibly be if not one , but several companies were engineering for it!!!!!!

So what if there's been a few bad renesis engines .. perhaps you should buy Chevy's rotary engine sports car.

As long as Mazda continues to build rotary engine cars ,and stays unique I'll continue to own nothing but Mazda vehicles. ( Haven't bought another brand in 8 years)

 

Even that concept (variable intake tuning) was first mass produced in a rotary.

 

Spinning Dorito fails!

No power source; it needs a big fuel injector, just off-centre, spraying on it!

 

Baked Doritos?

 

Evidence of this please?

The most common cause of engine failure in ALL designs is oil starvation. Because the rotary, BY DESIGN forces oil into the combustion chambers (albiet in miniscule amounts) it comsume oil. Failing to monitor oil level and maintain a proper oil level probably has done in more engines that any other cause. That said, this statement is an unsubtantiated opinion and not fact, just like your statement.

 

honda didn't start valve timing and lift, they just made it popular and catchy and named it vtec. ferraris were the first ones to use some sort of valve lift and timing from their camshaft designs/movement, so technically, vtec, mivec, vvti, etc. were all knock offs from ferrari.

back to what this thread is about:
no valves, no cams, no problem

 

+1 for the simplest way to say it.

Related story time: I was sitting at a light when I noticed a ~20 yr old guy in the car behind me pointing at my car while talking to his gf. As he was talking he made a little triangle with his fingers and then began moving one finger around and around. He gets points.

 

ahahaha im going to use that the next time someone asks me... probably tomorrow.

 

Well, you might want to take into account that mazda has admittedly had improper flashes for the car which caused some of the engine issues. They did a recall to fix this, and during this recall, if an engine was damaged it was supposed to have been replaced... So the recall might be part of the reason we see some of the engine replacements... just maybe...

 

Dorito = good, Pepto-Bismol bottle = better:

 

How about.. a weak gas guzzlin oil burning smooth high-revving engine?

ok go easy on me, i did complement its 'smooth high-revving' attributes

 

yes, it burns oil. yes, it drinks gas like a a football player drinks gatorade. weak? weak is how i would describe your girl's abilities in bed.

thanks for the smooth high revving compliment though. i also got the same compliments from your girl.
